Hej Hogmeister...
Det eneste formål med de 30 grains kugler i min gamle 22-250 var at se hvor høj hastighed jeg kunne nå op på... der var kune en enkelt ladning der var bare nogenlunde præcis, men den holdt også ca 10 mm på 100m (Ok for en non-customized out-of the box riffel)
And now to a favorite nit-picking exercise of mine:
What helps you most in combatting wind drift: Speed or high BC ?
Try and do the math yourself... Test this combination:
6,5x55mauser loaded to european pressures I can move an 140 grain Berger VLD out at 820 m/s in my rifle..
This load is not the most precise, but the fastest, it shoots 10 -12 mm (1/2") groups. The most precise Berger VLD load is slower at 795 m/s. this shoots 6 -7 mm groups (in the .2'es if you like in BR speak)
Now, my favourite load for this rifle uses a 107 grain Lapua Scenar, which has a lower BC than the Berger VLD, but it comes out at 910 M/s and shoots 7 -8 mm groups....
In this case the end result is : I'm better off with the lighter bullet at higher speed!!!
(the limitation is of course in range... realistic ranges on my grounds are less than 500 yds)
Now in the case of the 30 grain Berger MEF's the result is similar.. the speed outruns the lack in BC...
So, if the terminal effect of the bullet is "enough" (and belive me, the effect on crows is spectacular, just don't hit a blade of grass on the way out[
])
As it says on signs along the danish motorways: Farten dræber = Speed kills[
]
The 30 grain Bergers were bought for a special reason: My project handgun in .224Jet Magnum... and it works a treat!!!
This 10" barreled S&W model 53 (yes the Original!) shoots 1/3" groups at 100 m and launches the bergers at 844 m/sec
